User blog:Venmz/Help with breeding for shinies

Hey i have made this page because i think i am doing something wrong and i need players with experience that can help me and please correct me if i am wrong.

So i first started breeding for shinies when i got the shiny charm and bought the ro power for the x16 shiny chance. I breed and hatched eggs at the same time and only hatched about 68 eggs that way. Then i found out eggs are pre determined and i breed then put eggs in my pc got 2 boxes and 5 eggs which is 105 eggs per ro power. i hatched all of them no shiny. i did this about 5 times and im getting fustrated. I need help and thank you if you do respond.
